nginx;php

We’ll start by getting a web server and based on our requirements this will be a container running the official Nginx image. Since we’ll be using Docker Compose, we will create the following docker-compose.yml file, which will run the latest Nginx image and will expose its port 80 to port 8080:

web:
image: nginx:latest
ports:
– « 8080:80 »
Now we can run

docker-compose up
This should give you the default Nginx screen on port 8080 for localhost or the IP of your docker machine.

Now that we have a server let’s add some code. First we have to update the docker-compose.yml to mount a local directory. I will use a folder called code, which is in the same directory as my docker-compose.yml file, and it will be mounted as root folder code in the container.

web:
image: nginx:latest
ports:
– « 8080:80 »
volumes:
– ./code:/code
The next step is to let Nginx know that this folder exists.
Let’s create the following site.conf on the same level as the docker-compose.yml file:

server {
index index.html;
server_name php-docker.local;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
root /code;
}
If you don’t have a lot of experience with Nginx, this is what we define here – index.html will be our default index, the server name is php-docker.local

To activate this setup we need to apply yet another modification to our docker-compose.yml file:

web:
image: nginx:latest
ports:
– « 8080:80 »
volumes:
– ./code:/code
– ./site.conf:/etc/nginx/conf.d/site.conf
This will add site.conf to the directory where Nginx is looking for configuration files to include. You can now place an index.html file in the code folder with contents that is to your heart’s delight. And if we run

docker-compose up
again, the index.html file should be available on php-docker.local:8080.

Adding PHP-FPM

Now that we have Nginx up and running let’s add the PHP in the game. The first thing we’ll do is pull the official PHP7-FPM repo and link it to our Nginx container. Our docker-compose.yml will look like this now:
